EQ-5D-Y: EuroQol 5-Dimensions Youth; NB: hypercorrective Boston brace night shift; SSE: scoliosis-specific exercise; PA: adequate self-mediated physical activity; NA: not applicable—the distribution is a constant in self-care. Paretian Classification of Health Change: 1 The health state is worse in at least one dimension, and is no better in any other dimension; 2 the health state is exactly the same; 3 the health state is better in at least one dimension and is no worse in any other dimension; 4 the changes in health are “mixed”—better in one dimension, but worse in another.
